Tired of receiving spam, phishing attempts, or annoying messages in your Yahoo inbox? Whether it’s marketing emails you never subscribed to or messages from someone you no longer wish to hear from, knowing how to block an email on Yahoo can help restore peace to your digital life.

In this guide, you’ll learn step-by-step methods to block email addresses on Yahoo using both desktop and mobile platforms, plus how to report spam, filter messages, and manage your blocked list for better email control.

Why You Should Block an Email on Yahoo

Blocking emails can:

  • Stop repeat spam messages or harassment

  • Prevent phishing scams or malicious emails

  • Help keep your inbox clean and stress-free

  • Ensure that specific users or domains can’t contact you again

Yahoo makes blocking easy, whether you’re using the web interface or the mobile app.

How to Block an Email on Yahoo Mail (Web/Desktop)

36 1

Blocking someone on Yahoo via your browser takes just a few steps.

Steps:

Go to Yahoo Mail and log in

Open the message from the sender you want to block

Click the three-dot menu in the top-right of the message window

Select Block Sender

A confirmation pop-up will appear

Choose whether to delete existing messages from that sender

Click OK

Once blocked, that sender’s future emails will be moved to Spam automatically or be completely rejected depending on your settings.

How to Block Emails by Address (Using Settings)

You can also block specific email addresses manually through Yahoo Mail settings.

Steps:

From your Yahoo inbox, click the Settings gear in the top-right

Select More Settings

Go to the Security and Privacy tab

Under Blocked Addresses, click + Add

Type the full email address you want to block

Click Save

You can add up to 1,000 addresses to your Yahoo block list.

How to Block Emails on Yahoo Mobile App

While the mobile app doesn’t have a “block” button like the web version, you can still report or filter unwanted senders.

iPhone or Android:

Open the Yahoo Mail app

Tap on the email you want to block

Tap the three-dot menu at the top

Select Mark as spam

Repeat for other emails if needed

This sends the email to your Spam folder and trains Yahoo to filter similar messages in the future.

How to Unblock Someone on Yahoo

Changed your mind? You can remove a blocked email address any time.

Steps:

Go to Settings > More Settings > Security and Privacy

Look under Blocked Addresses

Click the Trash icon next to the email you want to unblock

The sender will now be able to contact you again

Note: Unblocking doesn’t restore previously deleted messages.

Use Filters to Auto-Delete Unwanted Emails

If blocking doesn’t work, you can set filters to delete emails as soon as they arrive.

How to Create a Filter:

Go to Settings > More Settings > Filters

Click Add New Filters

Name your filter (e.g., “Spammy sender”)

In the “From” field, enter the email or domain

Under “Then move the message to,” choose Trash

Click Save

Emails matching that filter will skip your inbox and go straight to trash.

Difference Between Block and Spam in Yahoo

Action What It Does
Block Email Prevents sender’s messages from reaching you
Mark as Spam Moves emails to spam and flags the sender to Yahoo
Filter to Trash Automatically deletes emails without blocking

For persistent senders, it’s best to block and filter at the same time.

Can You Block a Domain on Yahoo?

While Yahoo doesn’t let you block entire domains (like @spamwebsite.com), you can create a filter with domain-based rules.

Example:

In your filter’s “From” field, type:

sql
CopyEdit
ends with @spamwebsite.com

  • Set the filter to move those messages to Trash or Spam

This acts as a domain blocker even though Yahoo doesn’t call it that.

What Happens When You Block Someone?

What Happens When You Block Someone

Once you block an email on Yahoo:

  • Messages from that sender are moved to Spam or blocked completely

  • You won’t receive notifications for future emails from them

  • You can block up to 1,000 different email addresses

  • The sender does not get notified they’ve been blocked

Blocking is silent, effective, and can be reversed at any time.

Tips for Managing Unwanted Emails

Tip Why It Helps
Unsubscribe from mailing lists Reduces commercial clutter
Use Yahoo’s spam filter Automatically blocks known threats
Don’t open suspicious emails Prevents tracking and phishing attempts
Use strong filters Custom rules ensure control over your inbox

Staying proactive means fewer emails to block in the future.

Limitations of Yahoo Email Blocking

  • You can’t block an entire domain through the native block tool

  • The Yahoo mobile app lacks direct blocking features

  • Some spam may still bypass filters or blocking

  • You can’t block contacts based on keywords or topics—only email addresses

However, using a combination of blocking, filters, and spam marking gives the best results.
